NiCad, NiMH and LiON technology…what is the difference between them

There are three main differences between these three technologies:
NiCad – 1) will develop a HEAVY memory, 2) can charge 1,000 times before replacing the battery, 3) heavier in physical weight
NiMH and LiON – 1) will develop a memory but SIGNIFICANTLY less than a NiCad, 2) can charge 500 times before replacing the battery, 3) lighter in physical weight
Getting back to IMPRES batteries and the benefit of IMPRES technology in AUTOMATICALLY getting rid of battery memory and ‘which’ technology to use?  If the benefit of IMPRES is to AUTOMATICALLY get rid of battery memory and you can get 1,000 charge cycles out of a NiCad battery versus 500 with NiMH and LiON, then the choice is an easy one…STAY with the NiCad battery.  Yes, they might be a bit heavier but in this economy isn’t battery life lasting TWICE as long better on your budget?! Not all IMPRES batteries offer the NiCad technology but when they do we always recommend staying with the NiCad.


  1. Are you able to get NiCad batteries for cell phones and an IMPRES charger and if so are they only for Motorolla brand phones?

  2. Drew: another great question. Motorola IS the ONLY manufacturer of IMPRES batteries and chargers and as of now are only available for Two-way Radio Batteries. I don't believe that we will see this technology in cell phone batteries through Motorola or any other manufacturer in the near future. Most cell phone batteries come in LiON technology which does not retain the memory that a NiCad battery does. It is always good though to still try and drain the battery before charging's just good battery charging practice!
